“…Packet scheduling in a CDMA system poses more significant technical challenges, due to the additional dimension of power allocation for the non-orthogonal transmissions. Medium access with packet scheduling has been investigated for CDMA systems without time-division (TD) component [9], [10], and for hybrid TD/CDMA [11], [12], all for a single-cell CDMA system. To the best of our knowledge, very few works are available in the open literature for packet scheduling in a multi-cell system, taking into account the dynamics of intercell interference.…”

Abstract-In a wireless multimedia code division multiple access (CDMA) system, the resources in terms of transmission rate and power should be efficiently distributed to each user to guarantee its quality-of-service (QoS) requirements. In this paper, a resource allocation algorithm which combines packet scheduling and power assignment is proposed to achieve efficient resource utilization under QoS constraints. The packet scheduling is based on the fair packet loss sharing (FPLS) principle, and the power assignment is determined by the received power limited (RPL) scheme. The basic idea of FPLS is to schedule the transmission of multimedia packets in such a way that all the users have a fair share of packet loss according to their QoS requirements, which maximizes the number of the served users with QoS satisfaction. The RPL scheme minimizes the received power for each packet. Given the propagation path loss, it in turn minimizes the transmitted power as well. The intercell interference from the scheduled packets is also limited in order to increase the system capacity.Index Terms-Code-division multiple access (CDMA), fair packet loss sharing, packet scheduling, quality of service (QoS).

“…This protocol is suitable for any hybrid FDMAiTDMA or TDMAiCDMA scheme. However, in [33] the focus is restricted to the UMTS TDMAiCDMA TDD access selected by ETSI to be used in the UMTS unpaired bands.

This article presents a survey on medium access control protocols for multimedia traffic in wireless networks. A basic o v e r v i e w o f MAC p r o t o c o l concepts i s presented, a n d a f r a m e w o r k i s d e v e l o p e d o n w h i c h t o b a s e q u a l i t a t i v e comparisons. The M A C protocols covered in this article include third-generation TDMA and C D M A schemes intended for use in a single-hop wireless system. The operation of each protocol i s explained, and its advantages and disadvantages are presented. Finally, a qualitative comparative outline of the discussed protocols is provided, based on multimedia traffic requirements.ne of the driving forces of the next generation of wireless communication and computing networks is the promise of high-speed multimedia services. Third-generation systems, such as the International Mobile Telecommunication System (IMT-2000) network (formerly known as the Future Public Land Mobile Telecommunication System, FPLMTS) and the Universal Mobile Telecommunication System (UMTS), promise to provide multimedia services to mobile and fixed users via wireless access to the global telecommunications infrastructure [l, 21. The IMT-2000 is a universal, multifunction, globally compatible digital mobile radio system that plans to integrate all traffic types and all wireless systems under a common set of formats. The standards for IMT-2000 Available bit rate (ABR) traffic (non-time-critical data) Unspecified bit rate (UBR) traffic (file transfer, system backup, e-mail) In a wireless system consisting of a number of mobile terminals that transmit traffic of any type on a shared medium to a centralized base station, a procedure must be invoked to distribute packet transmission among all users. This procedure is known as a medium access control (MAC) protocol. MAC protocols are often classified according to their method of resource sharing, as well as their multiple access technology [4]. The resource sharing methods include dedicated assignment, random access, and demand-based assignment. Dedicated channels assign each user a predetermined and fixed allocation of resources, regardless of the user's need to transmit. Dedicated assignment schemes are appropriate for continuous traffic, but can be wasteful for bursty traffic. On the other hand, random access channels allow all users to contend for the channel by transmitting as soon as packets are available to send. Random access is suitable for bursty data traffic, but is not desirable for delay-sensitive traffic. Demand-based assignment schemes assign resources according to requests, or reservations, submitted by users. Once the requests are transmitted (using either dedicated or random access channels) and processed, users can be assigned resources according to the results. Demand-based channels are useful for variablerate traffic and the hybrid conditions of multimedia traffic. However, the additional overhead and delay caused by the reservation process can degrade performance.In addition to the resource shar...

Abstract-In the third-generation (and beyond) wireless communication systems, there will be a mixture of different traffic classes, each having its own transmission rate characteristics and quality-of-service (QoS) requirements. In this paper, a QoS-oriented medium access control (MAC) protocol with fair packet loss sharing (FPLS) scheduling is proposed for wireless code-division multiple access (CDMA) communications. The QoS parameters under consideration are the transmission bit error rate (BER), packet loss, and delay requirements. The MAC protocol exploits both time-division and code-division statistical multiplexing. The BER requirements are guaranteed by properly arranging simultaneous packet transmissions and controlling their transmit power levels, whereas the packet loss and delay requirements are guaranteed by proper packet scheduling. The basic idea of FPLS is to schedule the transmission of multimedia packets in such a way that all the users have a fair share of packet loss according to their QoS requirements, which maximizes the number of the served users under the QoS constraints. Simulation results demonstrate effectiveness of the FPLS scheduler, in comparison with other previously proposed scheduling algorithms.
